Lightroom CC: Tone curve and other bugs

After updating from version 1.3 to 1.4 the tone curve doesn't have a medium and strong contrast option. Also when you go from looking at the edited version of a picture to the original it shows the uncropped version of the picture rather than keeping it cropped and showing the edits vs non edits. Also when in the basic edits (light) if you shift click to have Lightroom automatically adjust the highlights, shadows, whites, and blacks nothing happens.
